What physical characteristics does the beluga whale have in order to survive in its environment?

Answer 1

A thick layer of blubber in order to keep it's internal temperature at a constant level. A blow-hole positioned at the top of it's head to breathe from the surface easily.
It also has a unique blood flow pattern that maintains a cooler temperature around its internal testes (to reduce sperm malfunction due to higher internal body temperature), and helps the whale lose excess heat through it's dorsal fin and tail flukes.
They also possess sonar to help them find prey and holes in the ice to breathe, as well as keep in touch with pod members.
